CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No.16/412,391, filed May 14, 2019, which is a continuation of InternationalApplication No. PCT/CN2017/108489, filed Oct. 31, 2017, claiming thepriority benefit of Chinese Patent Application Serial Number201611022276.5, filed on Nov. 16, 2016, the full disclosure of which isincorporated herein by reference.

BACKGROUND Technical Field

The disclosure relates to transmission schemes of radio signals inwireless communication systems, and in particular to a method and adevice for low-latency transmission.

Related Art

In conventional wireless communication systems based on digitalmodulation modes, for example, in 3rd Generation Partner Project (3GPP)cellular systems, transmissions of both uplink and downlink radiosignals are based on scheduling of a base station. Further, thetransmission at a given time is based on a currently configuredTransmission Mode (TM), and one time of transmission of one TransportBlock (TB) can employ one TM only—corresponding to one Downlink ControlInformation (DCI) format.

In the subject of reduced latency in Release 14, multiple DCIs areintroduced for one TB. Multiple DCIs schedule the transmission of one TBsimultaneously, so as to reduce latency and reduce overheads of controlsignalings. However, one TB can still employ one TM only.

New Radio (NR) access technologies are being discussed in the 3GPP.Typical application scenarios include Massive MIMO, etc. In view of themassive MIMO, Beamforming (BF) and beam sweeping based transmissionmodes will be broadly applied. However, for one Radio Frequency (RF)chain, multiple analog beams generated can be Time Division Multiplexing(TDM) only. When transmitting Reference Signals (RSs) based on beamsweeping, whether data can be multiplexed is a problem to be resolved.

SUMMARY

In view of the above problems, the disclosure provides a solution. Itshould be noted that the embodiments of the disclosure and thecharacteristics in the embodiments may be mutually combined if noconflict is incurred. For example, the embodiments of the UE of thedisclosure and the characteristics in the embodiments may be applied tothe base station, and vice versa. It should be further noted thatalthough the disclosure is originally designed in view of scenarios ofmulti-antenna transmission, the disclosure is also applicable toscenarios of single-antenna transmission, for example, short latencycommunications, Ultra Reliable Low Latency Communication (URLLC), etc.

The disclosure provides a method in a User Equipment (UE) for dynamicscheduling, wherein the method includes:

receiving first configuration information; and

receiving a first radio signal and a second radio signal in first timedomain resources and second time domain resources respectively.

FIG. 3 is a diagram illustrating an embodiment of a radio protocolarchitecture of a user plane and a control plane. In FIG. 3, the radioprotocol architecture of a UE and a base station (gNB or eNB) isrepresented by three layers, which are a Layer 1, a Layer 2 and a Layer3 respectively. The Layer 1 (L1 layer) 301 is the lowest layer andimplements various PHY (physical layer) signal processing functions. TheL1 layer will be referred to herein as the PHY 301. The Layer 2 (L2layer) 305 is above the PHY 301, and is responsible for the link betweenthe UE and the gNB over the PHY 301. In the user plane, the L2 layer 305includes a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303, and a Packet Data Convergence Protocol(PDCP) sublayer 304, which are terminated at the gNB on the networkside. Although not shown in FIG. 3, the UE may include several higherlayers above the L2 layer 305, including a network layer (i.e. IP layer)terminated at the P-GW on the network side and an application layerterminated at the other end (i.e. a peer UE, a server, etc.) of theconnection. The PDCP sublayer 304 provides multiplexing betweendifferent radio bearers and logical channels. The PDCP sublayer 304 alsoprovides header compression for higher-layer packets so as to reduceradio transmission overheads. The PDCP sublayer 304 provides security byencrypting packets and provides support for UE handover between gNBs.The RLC sublayer 303 provides segmentation and reassembling ofhigher-layer packets, retransmission of lost packets, and reordering oflost packets to as to compensate for out-of-order reception due to HARQ.The MAC sublayer 302 provides multiplexing between logical channels andtransport channels. The MAC sublayer 302 is also responsible forallocating various radio resources (i.e., resource blocks) in one cellamong UEs. The MAC sublayer 302 is also in charge of HARQ operations. Inthe control plane, the radio protocol architecture of the UE and the gNBis almost the same as the radio protocol architecture in the user planeon the PHY 301 and the L2 layer 305, with the exception that there is noheader compression function for the control plane. The control planealso includes a Radio Resource Control (RRC) sublayer 306 in the layer 3(L3).
